ABSTRACT
Objective: To rapidly identify the chemical constituents of Paeonia delavayi var. lutea roots by ultra-high performance liquid coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MSE) and UNIFI informatics platform. Methods: Time-dependent MSE data-acquistion mode was applied to acquire mass spectrometric data, and then the chemical constituents were identified by automatic identification and artificial identification. Results: Totally 57 compounds were identified, including monoterpene glycosides, phenolic acids, tannins, paeonols, and triterpenes. Conclusion: UPLC-Q-TOF-MSE combined with UNIFI database could be used to rapidly and comprehensively characterize the chemical constituents of P. delavayi var. lutea roots. This study provides a reference for quality control of P. delavayi var. lutea roots and clarifying the material basis of its efficacy.
